Growth and characterization of semiorganic crystal: Thiosemicarbazide lead nitrate (TSLN)

Semiorganic material of TSLN (thiosemicarbazide lead nitrate) has been synthesized in the ratio of 1:1. Thiosemicarbazide lead nitrate single crystals were grown from aqueous solution by slow evaporation method at room temperature. The good quality optically transparent single crystals were harvested and it is characterized by Single crystal XRD study revealed that materials crystallized with triclinic crystal structure and its belongs to centrosymmetric space group Cc and powder X-ray diffraction(XRD) is to confirm the crystalline nature of the crystal, using FTIR spectrum studies confirm the functional groups present in the grown crystal and the presence lead in the compound and the composition of the grown crystal were analyzed by energy dispersive analysis of X-ray (EDAX).UV–Vis–NIR spectra analysis shows good transmission in the optical region and near infra-red region and the optical constants i.e., absorption coefficient, extinction coefficient optical band gap and reflectance of the grown crystal were determined. The mechanical properties of the grown crystals have been studied using microhardness tester.
